To all whom t may concern.-

Beit known that l, ABRAM D. EMERY, of Taunton, Massachusetts, have invented certain Improvements in Spinning-Heads, of which the following is a specification.

This invention belongs to the class of spinning-heads heretofore invented by me in which the roving-bobbin is conoentrically supported in upright position within a drum surmounting a draw-roll frame carrying a system of pairs of draw-rolls which rotate upon horizontal axes, while the draw-roll frame, the drum, and the bobbin rotate upon a common vertical axis, and in which the roving is progressively unwound from the bobbin by centrifugal force and thrown tangentially' against the inner wall of the drum and thence led downwardly through a central vertical aperture in the lower head of the drum to the draw-rolls, by which it is drawn down at a prescribed rate and receives its twist at its point of delivery from the lowest pair of drawrolls.

The present invention embraces two improvements. First, the bobbin is carried upon a hollow spindle connected to and projecting upwardly from the draw-roll frame instead of, as heretofore, upon a spindle secured to and projecting downwardly from the top head of the said rotating drum, and, secondly, the shield for limiting the range of tangential throw of the roving is a hollow cylinder which may be open at its upper end and which is supported in a position concentric with the spindle either upon the frame of the machine or preferably upon the edge of a horizontal disk with which the base of the spindle is provided. As will be obvious, this construction greatly facilitates the application of the bobbin to or its removal from the spindle, lessens the weight of the rotating structure, and renders the exact centralization of the spindle with relation to the axis of rotation of the draw-roll-carrying frame more easily and certainly attainable than in my former construction, in which the spindle is secured to and depends downwardly from the top head of a rotating drum.

The accompanying drawings of a spinninghead, embodyingan illustration of the invention, are as follows, viz:

Figure l is an elevation in which there is conventionally represented an upright frame supporting a spinninghead and spooling mechanism, together with a driving-band engaging a whirl on the spinning-head, the horizontal members of the frame being shown in section. Fig. 2 is a top view of the structure represented in Fig. l. Fig. 3 is a horizontal section on the plane indicated by the dotted line a: a: on Fig. l. Fig. 4 is an elevation of one of the sides of the draw-roll frame which are at right angles to the axes of rotation of the draw-rolls, partly in section on the plane indicated by the dotted line y y on Fig. 6. Fig. 5 is an axial vertical section of the spinning-head, showing the cylindrical shield affixed to and rotating with the hollow bobbin-A holder. Fig. 6 is a transverse section of the spinning-head on the plane indicated by the dotted line ,c .e on Fig. 4E. Fig. 7 is a vertical section showing a portion of the frame adjoining the upper bearing of the spinning-head and illustrating the modication in which the cylindrical shield surrounding the roving-bobbin is supported upon the frame.

The drawings embrace a representation of a Spinning-head frame composed of two uprights A A', united by horizontal members B, C, D, E, and F, and a single example of a vertical spinning-head and winding appliances, the frame being adapted to support a multiplicity of such vertical spinning-heads and winding appliances arranged side by side, together with the necessary shafting and gearing for operating the same.

The spinning mechanism containing the present improvements consists, broadly, of a rotating spinning-head embracing, first, an upright hollow spindle H, connected to or formed integrally with the hollow trunnion Il and adapted to rotate upon its geometrical axis and to carry a bobbin of roving; secondly, adraw-roll frame I, provided at the top with the hollow trunnion I' for containing the hollow trunnion H and provided with a whirl I2 for engaging a driving-band I3, by which the said draw-roll frame and spindle are rotated upon a common vertical axis, the hollow trunnion H being secured in the upper end of the draw-roll frame by the transverse pin H2. Thirdly, a system of three superposed pairs J, J and J 2 of draw-rolls mounted in said draw-roll frame and rotated upon their parallel horizontal axes by motion derived from a toothed wheel K, mounted upon the lower end of the draw-roll frame and engaging a spiral worm or scroll Koccupying a horizontal plane and erected upon the top of the box K2, in which the hollow trunnion I4 at the lower end of the draw-roll frame has its bearing. This mode of imparting motion to the draw-rolls is the same as that shown and described in my pending application, Serial No. 624,112.

The upper bearing for the spinning-head is afforded by the removable box L, which is seated in a vertical aperture in the horizontal girder B and secured by the set-screw L', as shown in Fig. 5. The aperture in which the box L is secured is preferably made large enough to allow clearance for the draw-roll frame and the gearing mounted thereon, so that the spinning-head can easily be removed from or replaced in the frame if occasion arises.

The box K2, in which the trunnion I4 at the lower end of the draw-roll frame has its bearing, is seated in a vertical aperture in the girder C, wherein it is secured by the setscrew C', as shown in Fig. 1.

The bobbin-holder H is affixed to or preferably formed integrally with the cupped disk M, having on its under side the boss M', un-

derneath which is the hardened-steel ring M2 for bearing upon a system M3 of balls adapted to travel in the circular groove formed in the hardened-steel ring M4, seated in the top of the box L. In Fig. 5 a full-sized bobbin of roving is indicated by the dotted line f; Zt.

When the spinning-head revolves, the roving is detached from the bobbin by centrifugal force and is thrown against the cylindrical shield N, which may either be seated upon the cupped disk M, so as to revolve with the spinning-head, as shown in Fig. 5, or may be mounted upon the top of the girder B, as shown in Fig. '7, so that it will be concentric with the axis of the bobbin-holder.

The detached roving, as indicated by the dotted line O in Fig. 5, is led into the upper end of the hollow bobbin-holder H and downwardly therethrough to the draw-rolls. The lowest pair J of draw-rolls, as is customary, rotate slightly faster than the upper pairs of draw-rolls and deliver the roving through the hollow trunnion I4 to the usual tension device or so-called pig-tail P. As shown and described in my pending application, Serial No. 024,112, the twist is given to the roving at its place of exit from the lowest pair of drawrolls. From the pig-tail the roving extends down to the traverse-arm f, by which it is appropriately fed to the spool g, loosely mounted upon the rotating disk g and the stem g2, by the frictional influence of which the spool is rotated. p

The traverse-armf is loosely mounted upon the horizontal bar f ,extending entirely across the frame, and is vibrated by the heart-cam f2, affixed to the cam-shaft f3, also extending entirely across the frame. The disk g', carrying the spool g, is rotated by the band g2 from the pulley g4, affixed to the horizontal shaft g5, extending entirely across the frame.

The number of traverse-arms and the number of spools will of course equal the number of spinning-heads mounted upon the frame. Motion to rotate the cam-shaft f3 and the spool-driving shaft g5 is transmitted by any suitable gearing from the main driving-shaft Q, which is provided at one end with the fast and loose pulleys Q' and Q2. At appropriate intervals the main shaft Q has affixed to it the spinning-head driving-pulleys, one of which, Q3, is shown in the drawings as engaging the driving-band I for rotating the ad jacent spinning-head.

The shaft Q has affixed to it two adjoining pulleys i and t" of different d iameters for engaging the driving-belt 122, by which rotation is imparted to one or the other, as the case may be, of the pulleys i2 and 4, affixed to the counter-shaftj, which is rotated at different rates of speed, according to which pair of pulleys t and 3 or t" and t4 is engaged by the driving-belt 2. The counter-shaft j has its bearing in the upright A. As represented in the drawings, the pulleys t3 and t are arranged upon the part of the counter-shaftjl which projects inside the standard A. On the portion of the shaft j which projects outside the upright A there is affixed the pinion j',which engages the change-gearj2, loosely mounted upon the adjustable stud j. Aixed to the gear 7'2 and also loosely mounted upon the stud js is a pinion L7'4, which engages the gear j, afxed to the spool-driving shaft g5. The stud js is given the capacity of adjustability for the purpose of permitting the removal of the gear j2 and its attached pinion jl and the substitution of others in their places, as occasion may demand, in order to communicate to the spool-driving shaft g5 the required rate of rotation. To this end the stud L7'3 is carried by the upper arm of the lever k, which is loosely mounted on the counter-shaft '7' and has its lower arm 7o concentrically slotted to admit the set-screw 7a2, by the screwing home of which the lever 7c is clamped to the upright A. The upper arm of the lever 7.: is radially slotted to admit the screw-threaded end of the stud js and is adapted to engage the jamnut k3, by means of which the upper arm of the lever Zt is firmly clamped against the collar 7a4, which is affixed to or integral with the stud js. The gear and pinion are retained on the stud js by the usual washer and cotter 765.

The outer extremity of the counter-shaft j has aixed to it the worm Z, which engages and drives the worm-wheel Z', secured to the outer end of the transverse counter-shaft Z2, mounted in suitable bearings in the bracket Z3, affixed to the upright A.

The inner end IOO IIO

of the transverse Counter-shaft Z2 is provided with the worm Z4, which engages and drives the worm-wheel Z5, affixed to the cam-shaft f3.

It will of course be understood that the described trains of gearing for rotating the camshaft f3 and the spool-shaft g5 are herein shown and described merely for the purpose of illustration and that the invention is not limited to the particular forms of gearing shown.

Provision is made for stopping the rotation of any spinning-head when its bobbin runs out or the yarn breaks. To this end there is provided upon the driving-shaft Q, immediately adjoining each of the pulleys Q3, ,a worm m, which drives the horizontal gear lm', the face of which is provided with a crank-pin for engaging one 'end of a pitman m2, the opposite end of which is pivoted to and imparts endwise reciprocating motion to the tripperbar m3. The driving-band 3 is held taut and made to rotate its spinning-head by means of the tightening-pulley n, mounted upon the inner end of the hand-levern. The tightening-pulley n is retained in its band-tightening position by the engagement of the shoulder n2 on the hand-lever with the horizontally-extending arm ofthe trigger o, the downwardly-extending arm of which is perforated to allow the passage through it of the adjacent end of the tripper-bar m3. The weighted arm o of the trigger may be operated manually if it should be desired to stop the rotation of the spinning-head. The automatic stopping of the spinning-head when the yarn breaks or the roving runs out is effected by means of the detector-lever p, the longer arm p of which is provided with an eye or hook which normally engages the yarn immediately below its point of delivery from the spinning-head. When the detector-lever p is thus engaged, its shorter arm p2 occupies the position in which it is shown in Fig. l, in which it is below the path of movement of the tripper-bar m3,' but if the yarn breaks or gives out the detector-lever p is released to the influence of gravity and its shorter arm p2 then swings upward against the down` wardly-proj ectin g arm of the trigger, in which position it receives the impact ofthe tripperbar 'm3 and by communicating the motion thereof to the trigger o releases the trigger from the shoulder n2 and permits the tightening-pulley n to fall, and thus slack the band I3, so that it will cease to rotate the spinninghead.
